This conference represents a joint effort to bring close together Spanish and Portuguese researchers in the different areas of human perception. This edition takes place in the grounds of the Azurém campus of the University of Minho and has the special support of the Computer Graphics Centre which hosts the conference in its modern facilities. The program of this edition is diverse and encompasses fundamental, applied, and clinical aspects of research in several aspects of human perception. We will also have the opportunity to visit the Laboratory of Visualization and Perception, a large facility for visualization and precise psychophysics recently implemented in the Centre of Computer Graphics. We wish you all a great conference! The Organizing Committee 4 Committees Organizing Comittee • Sérgio M. C. Nascimento, Ph.D. (Department of Physics, University of Minho, Portugal) • Jorge A.
